Chapter 5 - Force and Motion-I - Questions: 8a

Answer

Graph A corresponds with situation 1.

Work Step by Step

Graph A shows a constant x-component velocity. A constant velocity is only created when there is either no force, or equal and opposite forces, acting on an object in motion. The only situation that displays equal and opposite forces in the x direction is situation 1. 5N to the right and a net total of 5N to the right, meaning no acceleration.
